以特定间隔更新列表视图

Question

Having a list view with some details, I have data inflated in list view from server. So on create of activity I have called a api to get data and inflated to list view once. And also pagination is there in list view,so on scroll to last item it will again call api for next page and append data of next page at end of list. This works fine. But what I want is kind of auto referesh of list view data at some interval. Means list view to have kind of updated data.How I need to architecture my activity to obtain solution I want.

Try this:

Handler mHandler = new Handler();
Thread downloadThread;

boolean isRunning = true;

In onCreate() :

downloadThread = new Thread(new Runnable() {
            @Override
            public void run() {
                // TODO Auto-generated method stub
                while (isRunning) {
                    try {
                        Thread.sleep(10000); // run at every 10 seconds
                        mHandler.post(new Runnable() {

                            @Override
                            public void run() {
                                // TODO Auto-generated method stub
                                // Write your code here to update the UI.
                                updateListData();
                            }
                        });
                    } catch (Exception e) {
                        // TODO: handle exception
                    }
                }
            }
        }); 

       downloadThread.start();

Thanks.

在Activity的onCreate()创建一个Hanlder ，然后从post() ， postAtTime()或postDelayed()选择适合您的内容 ，然后调用您的refresh方法。

use following to update listview

 new Handler().postDelayed(new Runnable() {

        public void run() {
            // TODO Auto-generated method stub
            callFunction();
        }
    }, 3000);
